Battery continually drained in saab 9-3 1999.

Hi and welcome to TSF :wave:

Have you had the battery checked to make sure in fact is good?

Hi helbacha

Give a quick scan into your interior lights see that all dimmer switches and dome lights are in the off position. Look at your door jamb switches see that they are not broken and shorting to ground. Remove the positive terminal from your battery and connect a test light, connect the alligator clip to the positive terminal and the test light tip to the positive battery post. With all doors closed and ignition on does the test light turn on bright ? If it does there is a short circuit which you will have to disconnect your fuses 1-by-1 to locate where the short is. When the test light goes off, note the fuse amperage and where it connects to.


Note: Car radio's do have some parasitic load which is considered normal, anything above its parameters will kill the battery.
